"Days after the launch of ATI X1K series, and availability of
CrossFire Technology, ATI has released their monthly 5.10 (October)
update for their Windows CATALYST users and have accompanied the release
with a new build of their Linux drivers. These drivers are dubbed
v8.18.6 and are available in RPM format as well as through ATI's
relatively new driver installer program that we've been accustom to
seeing since their v8.14.13 release."
